What is Scope (Wallach & Scholz, 2012)?

Establish a common ground between the contributing stakeholders:
  • Goals

What is the goal of the Design activity in the UCD cycle?

Transform all the findings form previous phases in a tangible artifact:

- conceptual design
- visual design

What is done when you Validate?

The technology needs to be iteratively validated against goals.

What is done in the Deliver phase and what not?

The results of the design (like mock up) phase are deliverd, but this does not include  implementation of technology or final evaluation

The question on the page originate from the summary of the following study material:
